Pixie Lott shows off her toned stomach in crop top and high-rise jeggings as she leaves Puttin' On The Ritz performance

She's been earning rave reviews for her appearance in the all-singing, all-dancing production of Puttin' On The Ritz.

And it was another successful evening for Pixie Lott, who couldn't contain her glee as she left the New Wimbledon Theatre on Saturday following another crowd-pleasing show, her last in London before the musical hits the road.

The 24-year-old pop princess showed off her toned stomach in a retro blue crop top and high-waisted stonewash jeggings as she left the venue.

The Mama Do hit-maker's blonde locks were coiffed in a low ponytail with a bouffant curl at the front.

She set off her casual look with neon orange-tipped espadrilles as she headed home to her boyfriend Oliver Cheshire.

Pixie came over a little camera shy as she exited the theatre to a crowd of excited fans clamouring for an autograph.

Her stage show sees her reunited with Strictly professional dancers Kristina Rihanoff, her pro partner Robin Windsor and Trent Whiddon.

Following her brush with reality TV last year, Pixie is now back in the studio working on her next album.

She recently confessed she's been working with pop producer Cathy Dennis, who has masterminded hits like Katy Perry's I Kissed a Girl, Britney Spears's Toxic and Kylie Minogue's Can't Get You Out of My Head.

'We've only just started working together, but we've already come up with some great lyrics and a big sound', she said according to josepvinaixa.com. 'Fans can expect a departure from my earlier stuff.'

While partying with Miley Cyrus last week, the Nasty singer ended up exposing more than she intended thanks to the pesky paparazzi.

The 23-year-old has opened up about the perils of an innocent Kodak moment turning into an impromptu flesh-baring fest with just one flash of a photographer's camera.

In an interview with 4Music presenter Miquita Oliver, Ms Lott confessed that celebs have more to worry about than the clichéd question 'does my bum look big in this?' while selecting an outfit for a red carpet event.

“You always have to be careful about the nipples and boob situation”

When asked about the white gown she wore to the BRITs, Pixie flushed: "It was last minute as I was really stuck. It was backless so you always have to be careful about the nipples and boob situation."

Revealing further #firstworldprobs, Pixie continued: "With the flashes you just never know what's going to come out in the pictures.

"I tried those nipple petal things, but you look through the dress and you can just see circles. Which is worse!"

Simon Amstell's former Popworld co-host also quizzed Pixie about naked video shoots and how she achieves her retro chic look.

The show also contains the Made In Chelsea cast deciding who is the most vain, which could take some time so we suggest you make yourself comfortable.

Pixie wore her long blonde hair in an intricate 1940s up-do, decorated with butterflies.

The show, which features the songs of Irving Berlin, George Gershwin and Cole Porter, opens at the New Wimbledon Theatre on Wednesday before heading out on tour.

For the dates in Wimbledon and Newcastle, Pixie will sing and dance in the show with other big names from Strictly Come Dancing, to be announced for future dates on the tour.

Pixie recently returned from a glamorous week in Cannes with her model boyfriend Oliver Cheshire.

After having been an item for around five years, it's clear the young couple are still into each other - they're also planning their future together.

Speaking to the latest issue of Look magazine, Pixie admitted that they can't really plan date nights thanks to their hectic schedules, so were no doubt happy to be together on Wednesday for a rare evening of fun.
